/* Admin panel styling.
 *
 * Self-hosted, no CDN and no build step. Iranian networks reach the usual
 * CSS CDNs unreliably, and a panel that renders as unstyled text on the day
 * the link fails is worse than one that ships its own 8KB.
 *
 * RTL throughout: `direction: rtl` on the root, logical properties
 * (margin-inline, padding-inline, border-inline) everywhere else, so nothing
 * needs a mirrored stylesheet.
